GUARD-RAIL CLAMP.

Patented July 16, 1907.

Application filed October 8, 1906. Serial No. 338,045.

To all whom it may concern:

Be it known that I, WILLIAM C. BoswELL, a citizen of the United States,residing at Chattanooga, in the county of Hamilton and State ofTennessee, have invented certain new and useful Improvements inGuard-Rail Clamps; and I do declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it .appertains to make and use the same.

This invention relates to improvements in guard rail clamps.

Theobject of the invention is to provide a guard rail clamp by means ofwhich the guard rail will be securely held in proper position withrespect to the track rail and firmly braced, means being providedwhereby the fastening bolt will be securely held against movement.

With the above and other objects in view, the invention consists ofcertain novel features of construction, combination and arrangement ofparts, as will be hereinafter described and claimed.

In the accompanying drawingsz-Figure l is a perspective view of aportion of'a railway track rail and guard rail, showing the applicationof the invention thereto; Fig. 2 is a vertical sectional view throughthe track and guard rails and the clamp for holding the same; and Fig. 3is a detail, perspective view of one of the clamps removed from therail.

Referring more particularly to the drawings, 1 denotes the track rail,and 2 denotes the guard rail, the opposite ends of which are turnedinwardly in the usual manner. Between the track rail 1 and the guardrail is arranged a centrally-disposed spacing block 3 and end spacingblocks 4.

Arranged beneath the track and guard rails are combined chairs andclamping devices 5, each of which comprises a base portion 6 adapted torest upon the ties. The ends of said base portion 6 are provided withspike holes, through which spikes are driven into the ties to secure theclamp in place. On the base portion 6 adjacent to the inner side of oneend is an integrally formed upwardly-projecting bracing and clampingblock 7 to fit over the flange of the guard rail and to bear against theWeb and under side of the head of the same said block being providedwith a straight face 8, and with a longitudinally-disposed bolt hole 9.Adjacent to the other end of the base portion 6 is formed a clampingblock 10 that is formed on its inner side to fit over and engage theflange on the outer side of the track rail. The block 10 has formed inits upper side a longitudinally-disposed groove or channel 12,

in which is adapted to be seated the head 13 of a fastening bolt 14which is adapted to be inserted through the web of the track and guardrails, the spacing blocks between said rails and through the bolt hole 9in the block 7 on the opposite end of the base portion 6.

There may be any desired number of spacing blocks arranged between therails, and one of the clamping devices 5 is preferably arranged on therails opposite each of said spacing blocks, the latter being held inplace by means of the bolts 14 passed therethrough and through the railsand the clamping block 7, as shown. The head of the bolts 14 aredisposed in the grooves or channels 12 in the blockslO, therebypreventing said bolt from turning. The opposite threaded ends of thebolts project beyond the outer straight faces of the blocks 7, and areadapted to receive nuts 15, which are screwed thereon and intoengagement with the straight faces 8, thereby securely holding all ofthe parts in position.

From the foregoing description, taken in connection with theaccompanying drawings, the construction and operation of the inventionwill be readily understood without requiring a more extendedexplanation.

Having thus described my invention, what I claim as new and desire tosecure by Letters-Patent, is

l. A guard rail clamp having formed thereon guard rail and track railclamping blocks, and means formed in one of said blocks to receive andhold the head of a fasted ing bolt, substantially as described. 7

2. A guard rail clamp comprising a base portion adapted to be secured toa tie, a clamping and bracing block formed integrally with one end ofsaid base portion to engage the flange and web on the outer side of theguard rail, and a clamping block formed integral with the op posite endof said base portion and having formedtherein a longitudinally-disposedgroove or channel to receive the head of a'fastening bolt, substantiallyas described.

3. A guard rail clamp comprising a base portion adapted to be secured toa tie, an upwardly-projecting guard rail bracing and clamping blockformed integral with one end of said base portion, said block havingformed therein a longitudinally-disposed bolt hole, a track railclamping block formed integral with the opposite end of said baseportion and having therein a longitudinally-disposed groove or channelto receive the head of a fastening bolt, a spacing block having a bolthole, and a fastening bolt adapted to be inserted through alined holesin the flanges of the rails and in said spacing block and the guard railclamping block; the head of said bolt being disposed in the groove orchannel in said track rail clamping block, substantially as described.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses. v
